Many flea extermination programs fail because of improper application. The most common mistake is to use a pump type sprayer. This type of application rarely works.
For best results, use a hose end sprayer when treating lawns, outdoor dog runs, kennels or other areas where fleas are found outside. There are many hose end sprayers to choose from.
We have found best results using either a 20 gallon hose end or a Dial-A-Mix type sprayer. Make sure that the sprayer you choose has a siphon tube that allows the sprayer to empty its contents. A “no-clog” sprayer does not use a siphon tube and does not give you accurate application of pesticides. Use your no-clog sprayer for water soluble fertilizers, not for pesticides on your lawn.
Outdoor flea or tick treatments require large volume of product which cannot be applied using a hand held pump type sprayer. Always use your hose end sprayer when treating outdoor infestations.
Choose your flea control products carefully. Many over-the-counter products on lawn & garden store shelves do not contain the correct amount of the best active ingredients. Two pest control products being used by pest control operators are Permethrin Pro and Talstar. Permethrin Pro has a faster knock-down of most insect pests and Talstar tends to last longer. Either product will do a good professional job of killing fleas, ticks, ants, molecrickets, chinch bugs and other lawn pests. If you do not have an existing flea problem but would like to take preventative measures go to the Outside Flea Prevention page.
Outdoor flea treatments should be made at the same time as inside flea treatments as well as treating your pets with topical flea and tick products.
Flea problems (both indoor and outdoor) are rarely cured in one application. Repeat applications are usually required. In most flea infestations, two applications should be made. Make your pesticide applications about 10 days to two weeks apart.
Patience is the key to safe pest control. You will usually see fleas hatching and hopping in your lawn (as well as in your home) the very day after your pest control treatment. This is due to the nature of the flea pupae or flea cocoons.
[The four stages of flea development: flea egg, flea larvae, flea pupae, adult flea.] The flea pupae is water tight, allowing no pesticides (or IGR) to penetrate through to the dormant, immature fleas.
As the adult fleas emerge from their cocoons they will come into contact with your insecticide and die within a couple of hours. What is frustrating to most people is to see fleas constantly hatching every day. This is normal! Wait at least 7 days before making a second application outdoors, 14 days indoors. Spraying every day or mixing pesticides stronger than label instructions dictate will not kill fleas any “deader” than dead. Be patient. Severe flea problems could take as long as 8 weeks to bring under control.
